Sizing

Find the Right Fit for Your Dog

For the best fit, we recommend measuring your dog instead of guessing based on breed or weight. Every dog is built differently, and accurate measurements ensure your gear fits properly.

What to Measure

Neck – Around the base of the neck where the collar sits
Chest – Widest part of the chest, just behind the front legs
Length – From the base of the neck to the base of the tail

How to Measure

Have your dog standing naturally on all fours
Use a soft measuring tape (or string + ruler)
Keep the tape snug, not tight
Leave room for two fingers for a comfortable fit

Between Sizes?
If your dog is between sizes, consider their build. Slim dogs may size down, while broader or thicker-coated dogs may need to size up.
